Sharing the dial-up connection of a PC laptop--either wired, or wirelessly

Question

Hello, fellow Mac users! I just got my first Mac--a beautiful 1.83 GHz MacBook. I LOVE the switch to OS X from Windows XP.
Anyway, here's problem:
I am leaving on vacation, and, unfortunately the resort at which we are staying does not have Internet Access, so I am forced to use dial-up. Unfortunately, since I have heard very bad reports about the Apple USB Modem, I can't get a modem for the MacBook itself, so I will use my PC laptop's modem. The PC Laptop is a Windows XP Pro machine. So, here's the problem--try as I might, I just cannot get the darn PC laptop to share its dial-up connection; either over a ethernet cross-over cable, or adhoc Wi-Fi.
So, please help me get this to work, or I will be forced to use a PC laptop to check e-mail, RSS feeds, and anything else online.
Thanks in advance! (And thanks, Steve Jobs, for helping to create some of the best computers out there!)

Answer 1

Here is from the help support on xp :
Configure,a dial-up
connection, click the connection that you want to
configure, and then, under Network Tasks, click Change
settings of this connection.
Do one or more of the following:
To configure dialing devices that your computer uses
to make a connection (a modem, for example), phone
numbers, host addresses, country or region codes, or
dialing rules, click the General tab.
To configure dialing and redialing options, or X.25
settings, click the Options tab.
To configure identity authentication, which is a way
to help verify your computer’s identity when making a
connection, data encryption (which codes the content
so that it’s less likely to be readable by someone
other than the intended recipient), or terminal window
and scripting options, click the Security tab.
To configure the remote access server that you want to
connect to and protocols (the format that your
computer uses to communicate with other computers)
used for this connection, click the Networking tab.
To turn Internet Connection Sharing on or off or
configure your computer to establish a dial-up
connection automatically, click the Advanced tab.
When you run the
Network Setup Wizard and enable Internet Connection
Sharing, some protocols, services, interfaces, and
routes are configured automatically. The following
table describes these configured items.
Configured item Action
IP address 192.168.0.1 Configured with a subnet mask
of 255.255.255.0 on the LAN adapter that is connected
to the home or small office network.
Autodial feature Enabled.
Static default IP route Created when the dial-up
connection is established.
Internet Connection Sharing service Started.
DHCP allocator Enabled with the default range of
192.168.0.1 and a subnet mask of 255.255.255.0. Unique
addresses in the range 192.168.0.2 to 192.168.0.254
are allocated to private network clients.
So try to use dhcp on your network setting or something between those range listed above with a cross over cable (make sure the cross over cable has good connection).
